About LM Studio

LM Studio is a desktop app for discovering, downloading, and running local LLMs, with a chat UI and an OpenAI-compatible server.

It runs models entirely on your local hardware, so prompts and data never leave your machine, and it exposes a local OpenAI-compatible API server for integrating with other applications. A built-in model browser lets you find and download open-source LLMs, and it ships as a native app on macOS, Windows, and Linux.

It fits people who want private, offline model use or a local endpoint for their own apps. It is a weaker fit if you want open-source software, since the desktop app is proprietary, if you need hosted models, since it does not provide access to GPT-4 or Claude, or if your machine is limited, since inference speed and model size are constrained by your local hardware.

LM Studio keeps inference on your own device rather than on a hosted service.
